WebRadio waves are just another form of light that travels at the same speed; 186,000 miles per second. Radio waves can get to the Moon and back in 2 ½ seconds or circle the Earth in 1/7 second. The energy in a radio wave is partly electric and partly magnetic, appearing as an electric field and a magnetic field wherever the wave travels. WebAnswer (1 of 3): I believe you are asking about the AM and FM bands, rather than AM and FM transmission, which is a method rather than a band or frequency. The AM band, called MW for mediumwave, in much of the world, runs variously from 530KHz to 1710KHz (or .53 to 1.71 MHz). The FM bands in mos...
